PAPER FASTENER Filed Got. 10, 1942 2 7 Inventor Orland A ffren/l e Patented Aug. 10, 1943 UNITED STATE-S P NT o Price} 1 RAPER. FASTENER Orland A.Krenke, Martins Ferry, Ohio Application October 10, 1942;,Serial No. 46l,591 3 Claims. (01. 2447) The present invention relates to new and useful improvements in fasteners for holding several sheets of paper together andthe invention has for its primary object to provide a non-metallic paper fastener of this character designed for use as a paper clip and embodying means for firmly securing the sheets of paper together without mutilation or injury thereto.

A further object of the invention is to provid a device of this character of simple and practical construction, which is neat and attractive in appearance, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside inthe details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawing forming part hereof, wherein'like numerals refer to like parts throughout and in which:

Figure 1 is a fragmentary rear elevational view showingithe paper fastener in position for securing the corner of two sheets of paper tgether.

Figure 2 is a similar view showing the front side of the fastener. v

Figure 3 is a similarview showing the fastener in a partly open position. 7

Figure 4 is a sectional view taken substantially on a line i.4 of Figure 1. V

Figure 5 is a plan view of the-fastener in its partially open position removed from the paper, and

V Figure 6 is a. plan view ofthe blank fromwhich the fastener is formed.

Referring now to the1drawing in detail wherein for the purpose'of illustration I have disclosed a preferred embodiment of the invention, the-numeral 5 designates the blank generally from After the flaps I!) have been folded uponthe bottom portion 5 and secured in position the 7 corner of the paper designated at l5is inserted which the fastener is constructed, the blank being composed of substantially stiff paper, or similar nonmetallic material and is preferably of rectangular form and includes a back portion 6 along the lower edge of the material at the corners of which are indicatedthe diagonally extending fold lines 1 connected at their inner ends by the transversely disposed fold line 8.

At the junction of the fold lines 1 and 8 the material is severed to form slits 9-9 which extend in diverging relation to form the flaps l0.l 0' adapted for folding along the fold lines. 'lupon, the bottom portion 6 as will be apparent from an inspection of Figure 5 of the drawing.

The outer edges of the flaps in are formed with slits ll adapted for inter-connecting the flaps to I secure the same against separation. The material between the slits- 9 forms a tongue I2 connected to thebottom portion .6

along the fold line 8 and the tongue 12 is provided at its outer edgewith a flap l3 foldable along the fold line designated at l4.

between the portion 6 and the connected flaps it,

' in the manner indicated in Figure 3 ofthe drawj 'ing; the corner of the paper projectingthroughl and beyond the flaps lil to-partly lie upon the tongue l2. paperare then folded upon the flaps I!) and the extension. I3 folded along the fold line H upwardly under the flaps l0 as will be apparent from an inspection of Figures 2 and 4 of the drawing. e

In this manner twoor more sheets offpaper maybe securely attached togetherto prevent separation thereof.

When itis desired to separate the paper the extension l3 of the tongue. I2 is withdrawn from I under the flaps ill and the paper may thenbe, withdrawn from the fastener. I

It is believed the detailsof construction, ad-i vantages and manner of use of-the-device will be readily understood from the 'fQregQingWithout further detailed explanation. ,7 Having described the invention, what isclaimed as new. is:

l. A paper fastener comprising aisheet of fold able material including anf'elongated. central 1 portion, a pairoftabs at the side dges thereof f, and adapted for foldin -in overlapping relation upon thejcentral portion, means for securing free 'l ends of the tabs to each other to forni a continu ous fiat band adaptedfor receiving acorner of a stack of vpapersheets, a tongue on the-upper edge of the central portion and foldable upon the tabstogether with saidcorner' of the paper and afoldable extension on said tongue adapt-edfor folding under the tongue andthe tabs. V, 2 Apaper fastener comprisinga sheet of foldable material including an elongated central portion, a pair of'tabs at'the side edges thereof and], adapted for folding inoverlapping relation upon the central portion, said tabs having inter-engag ring slits adapted for securing the tabs together .to form a continuous flat band adapted for receiving" a corner of a stack of paper sheets, alto-ngueion the upper edge of the central portion and foldable upon the tabstogether with said cornerv of the. paper sheets, and a foldable extension on the, tongue adapted for engaging underithe tongue I and the tabs.

3. A paper fastener comprisinga sheet of, foldable material, tabs at the opposite side edges of the sheet foldable upon the sheet toforma con tinuous band adapted to receive a' corner of a stack of paper sheets, means for securing" the free ends of the tabs to each other, and a ton ue v on the sheet foldable upon and under the-band for covering the connected ends of the tabs.
